How do you keep a secret from your best friend?

Dont......you should tell someone if you like them because you never know where it could take you. He might just like you too then you two will be happy together...if not then he is not a good friend.

NO. what you should do it HIDE it. if that's what you wanna do. i mean just don't COMPLETLEY fall all over him! but if you wanna take it that way then just act cute and flirty and see if he likes you backk. just don't globber him down with your love at first, you don't wanna ruin the friendship.
